1004 FAMILY XXXIII. — SALDID^E. 



dd. First or inner cell of membrane produced but slightly or not 



more than one-third its own length beyond the base of second. 



e. Corium with two distinct veins, the inner one forked toward 



apex, its branches reaching the membranal suture; apex of 



first or inner cell reaching or nearly reaching apex of second. 



III. Saldula, p. 1008. 



ee. Corium without distinct veins; elytra opaque; embolium a dirty 



white. IV. Micracanthia, p. 1013. 



cc. Sides of pronotum scarcely or not at all flattened; front callus of 



pronotum reaching to or nearly to the side margins; apex of 



pronotum narrower than head across eyes. 



d. Elytra glabrous, very shining, in brachypterous form convex and 



entirely coriaceous, the membrane scarcely differentiated; 



joints 3 and 4 of antennae distinctly thicker than 2; ocelli 



slightly separated. V. Lampracanthia, p. 1014. 



dd. Elytra sericeous, opaque, flat, piceous marked with white, the 



membrane distinct; joints 3 and 4 of antenna? not thickened; 



ocelli contiguous, set on a distinct elevation. 



VI. Chartoscirta, p. 1016. 



ua. Third and fourth joints of antenna? strongly swollen; pronotum 



with two prominent erect tubercles on front lobe; head narrower 



with eyes nearer together than in preceding genera (Subfamily 



Saldoidina?). VII. Saldoida, p. 1017. 



I. Pentacora Reuter, 1912, 7. 



This genus comprises four species above the average in size 

 for the family and usually found along sea beaches. The pres- 

 ence of five elongate equal cells in the wing membrane is the 

 one important character separating the group from the other 

 genera of the subfamily. In some of the cells there is often an 

 oblique vein running diagonally from one main nervure to an- 

 other, but this is not taken into account in fixing the number 

 of cells. 



KEY TO EASTERN SPECIES OF PEXTACORA. 



a. Upper surface dull, with appressed pubescence; elytra often with 

 short erect or inclined dark hairs. 

 b. Narrow side margins of pronotum and elytra with a row of very 

 short erect seta?; joint 2 of antenna? much longer than 3 and 4 

 united; length, 6.5 — 8 mm. 1141. signoreti. 



bb. Margins of pronotum and elytra without seta?; joint 2 of antenna? 

 equal to or shorter than 3 and 4 united; length, 5 — 6 mm. 

 c. Pronotum four times as wide as long at middle; elytra with nu- 

 merous short suberect hairs; color above mostly black; costal 

 area narrowly yellow with edge black. 1142. ligata. 



cc. Pronotum three times as wide as long at middle; elytra beset with 

 very short inclined bristle-like hairs; color above mostly dull 

 yellow; costal area concolorous. 1143. sphacelata.
